hello All, I've had this vox wah for a long time, i have a love hate relationship with it, it sounds great, but as sturdy as it looks its damn unreliable. First the toe switch got jammed, I got a new one on warranty. Then the holder for the battery was not making contact properly, bought a power supply. Then there was the fact that it would not engage, and sometime would... This last issue is quite weird, there seems to be no contact with the instrument input jack, so sometimes when I engage, the sounds just cut off - sometime it works as expected. WHen I do not engage, the signal goes through and I have sound... If I engage, and move the cable into the socket I do get some sounds but it does not stay in place since the pedal requires movements. Anyone seen that before? I don't want to keep pouring repairs and time in this unit if it ain't gonna solve the thing, but I don't wanna buy another wah just for that either. It does sound good when it works, but unreliability prevents me from taking it to gig. I feel I could just change the jack socket maybe?
